WHY USE THE PROTAC PM2.5 BREATHING MASK?
The advanced ultra lightweight soft foam material protects you from PM2.5 including dust, pollen and other airborne particles.
We also have RoHs certificates for the material we are using. This shows the material is environmentally friendly (note: The RoHs certificate meets European standards).
Not only is the mask lightweight and breathable, its also water resistant, unlike home-made cloth masks recommended by the CDC that can actually absorb moisture! The Protac PM2.5 is the preferred protection mask for Americans for comfort and protection!
WHAT IS PM2.5?
PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair. Commonly written as PM2.5, particles in this category are so small that they can only be detected with an electron microscope.
